Youth with autism spectrum disorders (ASD) without intellectual disability frequently experience academic problems, in part due to executive functioning (EF) deficits. There are currently no evidence-based interventions targeting academic EF skills for middle school youth with ASD. An intervention is currently in development. This paper reports on a "proof of concept" uncontrolled trial of the intervention, and focus groups with parents and youth to inform tailoring and adaptation of the intervention. Results of the trial suggest high feasibility/satisfaction, but a need for further adaptation to promote uptake by youth with ASD. Results from the focus groups confirmed the need for an intervention targeting academic EF skills, successful strategies in use, and the need to promote increased youth independence.
